Answer : 7 units

There are two ways you can solve this problem:

1st way - Subtract the T's x coordinate by r's x coordinate.

1-(-6) = 1+6 = 7

2nd way - Graph the points than count the units between them.

Answer:

The length of Side RT of the polygon is [tex]7\ units[/tex]


Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to


[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]


we have

[tex]R(-6,2)\\T(1,2)[/tex]  

substitute the values


[tex]d=\sqrt{(2-2)^{2}+(1+6)^{2}}[/tex]


[tex]d=\sqrt{(0)^{2}+(7)^{2}}[/tex]


[tex]dRT=7\ units[/tex]
